The HZI is continuously building a network of closely aligned strategic partnerships with universities, research institutions and hospitals. Its primary objective is to create synergies which establish the optimal conditions for an efficient transfer of knowledge from basic research to medical application: HZI Locations.

The Strategy of the HZI

Learn more about how the HZI, with its translational focus, will help to facilitate a faster and more targeted approach when it comes to fighting and preventing existing, emerging or recurring infectious diseases.

Working at the HZI

Around 900 employees in research, administration and infrastructure, and about 220 visiting scientists from 40 different countries are employed at the Helmholtz Centre for Infection Research. To ensure top quality research we need top quality employees. Your creativity and innovative capabilities are the basis for the long-term success of our work. That's why we undertake a great deal to attract the best people to us. Learn more about this.

Systems BiologyThe goal of systems biology is to describe the dynamic processes of life and of biological systems using mathematical models. In line with the foundation of the new Braunschweig Integrated Centre of Systems Biology (BRICS) we have compiled some background information about systems biology for you: To the systems biology feature.

How may individualisation find its way into care of patients with infectious diseases? This is the hot topic to be discussed during the international Herrenhausen Symposium on June 21-23, 2018, in Hannover.

Quick Test to Protect Children from Heart Disease

Joint European-Indian project targets deadly streptococci

A streptococcal infection may initially cause nothing more than a relatively harmless sore throat. It can, however, also lead to potentially fatal disease or lifelong disability. The outcome of a primary streptococcal infection depends on the strain of bacteria involved and frequently on the individual susceptibility of the patient. Scientists are now in the process to develop a test that will allow a quick diagnosis of streptococcal strains with potential to cause serious disease. Researchers are evaluating patient samples from India, where children in particular have a high frequency of exposure to strep-tococcal infections. The research project, known as ASSIST, includes partners from Europe and In-dia and is being coordinated by the Helmholtz Centre for Infection Research in Braunschweig. The European Union is funding the project with € 1.5 million.

Experts estimate that every year streptococcal infections occur in around 600 million people. Most of them experience brief throat or larynx infections. Some two million others, however, suffer from po-tentially harmful complications. Among these are so-called invasive illnesses which destroy cells and tissue, as well as rheumatic fever, which often leads to cardiac damage.

"Rheumatic heart disease, as a secondary effect of streptococcal infections, progresses very dramati-cally," explains Prof. Singh Chhatwal, departmental director at the Helmholtz Centre and coordinator of the ASSIST project. "It occurs primarily in children and frequently only a cardiovalvular trans-plant can save the child." Of the 15 million children worldwide suffering from rheumatic heart dis-ease, six million alone live in India. "The proper diagnostic methods are often lacking, resulting in inadequate treatment by antibiotics, “says Chhatwal, who was born in India and has first-hand knowledge of the situation there. There are grounds for optimism, however. Less than ten percent of the streptococcal strains are capable of triggering serious complications. "If we had an effective test to quickly diagnose whether a patient is infected with a dangerous strain, then we could concentrate on these cases," notes Chhatwal and points out that because the number of these cases is much lower than the total number of infected cases it would be much easier to introduce proper antibiotic treat-ments in poor countries.

Researchers working on the ASSIST project will be gathering information about the streptococcal strains prevalent in India over the next few years. They will also be examining the congenital dispo-sitions of people that make them more susceptible to dangerous pathogens. When this information is collected and evaluated they hope to develop a quick test for streptococcal infections. One avenue being explored is a process to identify specific surface molecules or genes that appear only in dan-gerous strains. Data will be gathered from patients in the age group most at risk in the most affected region of the world. "The Indian project partners," says Chhatwal," will take and evaluate throat swabs from 25,000 Indian school children."

The ASSIST research project

ASSIST is an acronym based on several first letters of the full project name: "Comprehensive approach to un-derstand streptococcal diseases and their sequelae to develop innovative strategies for diagnosis, therapy, pre-vention and control." Project partners, besides the Helmholtz Centre for Infection Research, include the Karo-linska Institut Stockholm (Sweden), the University of St. Andrews (Great Britain) as well as three Indian par-ticipants – the Postgraduate Institute of Medical Education in Chandigarh, the Christian Medical College in Vellore and the All Indian Institute of Medical Sciences in New Delhi. The European Union supports ASSIST as part of its program "Specific measures in support of international cooperation" (INCO).
